The Jamestown Machine Corp was found in an advertisement in Aviation and Aeronautical Engineering Magazine in May 15, 2017 when searching for Falcon Propellers, at the time when WWI equipment effort was increasing, particularly for mahogany propellers. The machine advertised was for rough shaping four propellers at once from one master template propeller. Their was no evidence found directly indicating equipment sales to Jamestown Propeller / Mantle manufacturing, however it would be logical. It is not known how many other propeller manufacturers may have purchased machinery. The firs attachment is the incorporation. Second is the address. Third is the advertisement. Fourth, fifth, and sixth attachments are a restored machine.
